A Series
PulsEater® Ceramic Composition
Available in E12 Ohmic values
The “A” Series non-inductive, ceramic composite
resistors are designed for a variety of applications
where high energy handling capabilities are crucial.
These resistors are ideal for any application which
is subject to surges, high peak power, or impulse
energy.
Their unique design allows uniform distribution
of energy throughout their structure which results
in low thermal stress. The high-temperature,
solvent-resistant epoxy coating carries a UL94V0
flammability rating which is suitable for almost any
environment.
*AZ style is provided with
dual terminal wires
